On our way home, coming through Jonesborough, I noticed a very bright star like light. At first I thought it might be some sort of light on a tower, as it was more prominent than the traffic lights. However, during the 15-20 minute drive home into the country it was apparent that it was not. I pointed the light out to my husband & stepson and they agreed that it was not a star or plane.The light remained stationary. There was a very dull dim light above it. We even flickered the truck lights at it to see if it would respond.As the three of us stared at it, it disappeared. The dull dim light remained for a while after and then it to disappeared.
